SADIRON CONSTRUCTION Original Filed April 9, 1923 Patented June 17, 1930JAY C. STEESE AND CHESTER A. HOFIE, OF AKRON, OHIO, ASSIGNORS TO THEAKRON LAMP COMPANY, OF AKRON, OHIO, A CORPORATION OF OHIO SADIRONeons-"rationals Application filed April 9, 1923, Serial No. 630,761.Renewed November 25, 1929.

The present invention relates to a sad iron which is heated by a fluidfuel, such for instance, as gasoline, kerosene, or any other similar oranalogous fluid fuel.

' The object of the invention is to provide an iron of the typedescribed, which is not unduly heavy, and one in which the fontcontaining the liquid fuel is not unduly large nor in the way of onemanipulating the iron.

A further object of the invention is to so support the font that it isheat insulated from its support.

A further object is to provide a construction in which the pipecontaining the regulating needle in association with the vaporizer, isarranged adjacent the burner so that after the burner has been inoperation for a short period of time, the heat from the burner willvaporize fuel in the fuel pipe ahead of the portion containing thevalve, and of course, ahead of the vaporizer, so that the valve isessentially regulating the passage of a gas rather than a liquid fuel,

and therefore regulation of the burner by the needle valve is moreeasily accomplished.

A further object of the invention is to provide a structure for a sadiron in which the burner may be started by preheating the fuel in avaporizer which is so arranged that the heat from a match may beemployed in the starting operation.

Further obects of the invention are to provide a structure which may bequickly and easily assembled within the body of the sad iron proper andwhich'permits ready removal of the vaporizer for replacement or repair.

Reference should be had to the accompanying drawings forming a part ofthis v specification, 111 which Fig. 1 is a perspectlve is usually thecase, with a heavy lower bottom portion 2 containing a proper amount ofmetal which will absorb heat and retain the same, which construction isof course common in sad irons generally.

Above the base portion 2 there is an outside wall 3, which extends allthe way around the base and upwardly for a suitable height. This wall atits upper edge receives a cover 4 whichis fastened to the walls 3 bymeans of screws or any other suitable fastening means. The cover 4carries the handle by which the sad iron is operated, the handle in thisinstance consisting of a U-shaped band of metal such as indicated at 5,which is fastened to the cover 4 in any suitable manner, as indicated at6. The free ends of the U-shapedmember 5 are secured to the ends of agrip member 7 which is preferably of material which isnon-heatconducting, such for instance as wood.

The font 8 containing the fluid fuel which is to be supplied to theburner that will be later described is supported by means of a curvedbracket 9 which at one end is secured directly to the portion of theU-shaped member, 5 which supports'the handle or grip 7. This bracket 9is spaced from the.

member 5 by means of asbestos packing, such as indicated at 10', whichis introduced between the bracket and the member 5 so that heat will notbe conducted the one from the other. The means by which the bracket 9 isfastened may be any desired means, as bolts 11.

The above, structure prevents the transfer of heat from the U-shapedmember 5 to the member 9, so that the fuel reservoir is well insulatedfrom the heat, which might otherwise be conducted to it from the sadiron when the same is in operation. This bracket 9 at its lower end isprovided with a U-shaped slot 12 which is adapted to receive a portionof a member secured to and extending downwardly from the font 8, whichmember at 'its outer surface is threaded and receives a knurled nut 13,this nut being so positioned that the bracket 9 at the slotted endthereof may slip above the nut 13 so that when the nut is tightened byturning the same it forms a means for effectually securing the font tothe bracket 9 in such a manner as to prevent its being easily detachedtherefrom except upon pos tive operation of the knurled nut 13.

Attached to the fixture on which the nut 13 ismounte dis a pipe 14 ofsmaller diam eter and this pipe is by means of a suitable cup, connectedwith an arm 15 which in turn forms a Y-connecti'on'with a tube 16. Thistube 16 receives a stem 17 which at its outer end has a knurled head 18.At its inner end the stem is pointed, as indicated at 19, andco-operates with a conical seat 20 formed at the end of the tube.

Attached at the end of the tube is a thinwalled pipe 21 of smalldiameter, which preferably'is formed approximately circular in shape.This pipe is the vaporizer, the function ofwhich is well understood bythose-familiar with the art. 7

Mounted within the walls 3 and attached to the base is a burner whichcomprises a long portion 22 having-slots or other orifices such asindicated at 23, by which the flame from the burning gas is directedupon heavy metal base portlon 2. The burner is roundedat one end andterminates in a short In the rear wall of the body portion of the sadiron there is a' vertical slot27 and this slot at its lower endiswidened out as indicated at 28.

The pipe 16 with its branch pipe 15 and the vaporizer 21 are a unitarystructure, and are capable of being inserted and removed from theinterior of the sad iron structure as a unit. It will be understood thatthis is a desirable and necessary feature because if there is anycarbonizing or clogging in the passageways, it will take place either inthe tube 16 or in the vaporizing coil 21, and therefore it is desirableand necessary :that these may beremovable and replace able in the eventthat 'necessity'demands.

The tube 16 and its branch pipe 15 are inserted through the lowerwidened portion 28 of the slot, and at the same time the end 21? of thevaporizing coil is inserted through the opening 26 in the mixer 25. Thisserves to definitely position the tube 16 and the vaporizing coil, andnot only is this structure'definitely fixed, but is definitely supported. The pipe 14, which is, as before explained, connected with thepipe 15, is definitely held in its position by virtue of the mounting ofthe font 8. when the font 8 is positioned and'held in its bracket 9, theconnection with the pipe 14 serves'to maintain the tubejl6 and itsallied parts in their definite mounted position. In fact, the font withthe pipe 14:, the tube 15, the tube 16, and the vaporizer, are removableas a unit from the remainder of the sad iron structure, and from theconstruction which has heretofore been described it will be seen thatthe various parts of this unit which have been described may bedisassembled. I I By reference-to Fig. 1 it will be seen that the tube16 extends within the body portion of the sad iron for a short distanceadjacent the burner 22, and additionally the 'vaporiz'- flng coil 21also extends adjacent to the burner. v 7

After the burner has become ignitedv and is functioning the heat fromthe burner will heat the tube 22, and will cause the formation of gas inthe tube 22 so that after the burner is going and functioning,instead ofliquid fuel being delivered through the valve seat which is controlledbythe valve rod 17 gas will be passing through and the vaporizing coil 21or generator will be practic'ally'acting merely to further heat the gasdelivered to it. I r

This has a distinct advantage in that it is a much easier matter toregulate the passage of a gas through the valve, and to obtain a niceregulation, than it is to regulate a fluid fuel. Of course, in the firstinstance and before the burner has sufficiently heated the tube 16, thefluid fuel will pass bythe valve in the tube 16, and will be regulatedby the valve stem 17, but the continued operation of the burner causesthe formation of gas within the tube 16 in the manner which has beendescribed. 7 r

In the starting operation of the'sad iron, the valve 18 is 'open to asufficient extent to permit fluid fuel to pass into the vaporizing coil21. Due to the fact'that this coil is of small diameter and of thinwalled material, which will easily absorb heat, it is possible to applythe heat of a match to the coil 21 and effectively vaporize ,the fluidfuel which is fed to it so that the gasified fuel passing from the coil21 to the mixer 25, is delivered into the burner 22 and will be thereignited.

Of course, the application of heat by means of a match to the coil 21 isonly required for a short time in order to supply the necessary heat forvaporizing the fuel in a preliminary way, for as soon as the gaseousfuel in the burner 22 is ignited and the heat. supplied to the vaporizer21, will continue the vaporizing of all fuel that comes to it.-

As before stated, after the burner has Therefore,

been functioning for a short period of time, the vaporizing effect takesplace in the tube 16, rather than in the coil 21. This has decidedadvantage for regulating reasons which have before been stated, and ithas been found after long trials that carbonizing effects are very slowin making their appearance.

In order to permit a match or other lighted paper to be introduced tothe coil 21, the side wall 3 of the sad iron is provided with an openingwhich is indicated at 28 in Fig. 4:.
